Specification of Letters Patent.

Patented July 21, 1908.

Application filed December 23, 1907. Serial No. 407,709.

To all whom it may concern:

Be it known that I, JAMEs TVILLIAM HAM- ILTON, a citizen of the United States, residing at i/Veatherford, in the county of Parker and State of Texas, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to baling presses and is more particularly an improvement upon the mechanism described and claimed in Patent No. 854,736, granted to, me on May 28, 1907.

The invention has reference more particularly to mechanism whereby the plunger within the press box may be quickly returned to its normal position immediately subsequent to its forward stroke, said mechanism being of a simple, durable and efficient character disposed at points within convenient access and constructed of few parts so that it will not readily get out of order.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a longitudinal section through a portion of the baling press embodying the present improvements. Fig. 2 is a plan view of the parts shown in Fig. 1.. Fig. 3 is a side elevation and showing the retracting mechanism in a position opposite to that shown in Figs. 1 and 2.

Referring to the figures by characters of reference, 1 designates the frame of the press designed to be mounted in any suitable man ner and having a press box 2 in which is mounted a plunger 3. This plunger is provided with a rod 4 having a head or enlargement 5 at one endand mounted to reciprocate within a gear compartment 6 located at one end of the press box 2. The rod 4 extends from the end partition 7 of said compartment and the walls of the compartment are preferably slotted longitudinally as indicated at 8 to receive a cross bar 9 which extends through head 5 and is designed to rea" ciprocate within the slot 8 and to project beyond the walls of the gear compartment.

driving shaft 10 extends transversely of the gear compartment and carries a pulley 11 designed to receive motion through a belt from any suitable sourceof power and a gear 12 is also secured to this shaft and drives a gear 13 disposed upon a countershaft 14 extending transversely of the gear compartment and carrying gears 15 located at opposite sides of the gear 13. Each of the gears 1.5

, meshes with a large toothed wheel 16 carried by a transverse shaft 17, the ends of said shaft extending beyond the side walls of the gear compartment 6 and being provided with similarly located cranks 18. The two wheels 16 are connected by pins 19 which act as teeth for meshing with teeth 20 formed upon the upper surface of the head 5. As shown in Fig. 2 this head and its rod 4 lies in the central longitudinal plane of the machine and the wheels 16 are disposed at opposite sides thereof. Sufficient pins 19 and teeth 20 are provided to drive the plunger the full length of its forward stroke and after this point is reached the gear formed by the pins 19 becomes disengaged from teeth 20 so that sepa rate means such as hereinafter described and which constitutes the present invention will operate to return the plunger to its initial position. In order to gradually increase the power during the pressing or forward stroke of the plunger the pins 19 are disposed along a curved line gradually approaching the peripheries of the wheels 16 and the teeth 20 are disposed on an incline so as to partly mesh wlth the pins.

Mounted upon the side walls of the gear compartment are supporting frames 21 and pivotally connected to the upper portion of each of these frames is a hanger 22. The lower ends of these hangers have longitudinal slots 23 into which the projecting ends of the cross bar 9 extend. Standards 24 are dis posed upon the walls of the gear compartment and are connected by means of springs 25 with the respective hangers 22 so as to hold the plunger 3 and head 5 normally in its initial or retracted position. Each crank 18 has awrist pin 26 which projects into the path of one of the hangers 22 and is designed to actuate it in the manner hereinafter set forth.

When the press is set in motion through gears 12, 13 and 14 and wheels 16, the eccentrically arranged pins 19 successively engage the teeth 20 of head 5 so as to drive the plunger 3 forward upon its pressing stroke. This movement will cause the cross bar 9 to swing hangers 22 forward against the stress of springs 25, the cranks 18 at the same time swinging downward out of the path of the hangers 22. As soon as the head 5 and plunger 3 have reached the limit of their forward stroke and the last in 19 of the series has become disengaged from teeth 20 the wrist pins of the cranks 18 swing backward over the shaft 17 and press against the hangers 22 and inasmuch as this power is applied close to the pivots of the hangers said hangers will be quickly swung backward to their initial positions, this movement being facilitated by the springs 25. It will thus be seen that immediately subsequent to each forward stroke of the plunger the mechanism will operate to positively and quickly return the plunger to its initial position so that ample opportunity is given between strokes for feeding material into the path of the plunger. It will be noted that all of this mechanism utilized for returning the plunger to its initial position is so located as to be readily accessible for repairs and inasmuch as the mechanism is formed of but few parts the same will be found very durable as well as efficient. Although two hangers and cranks have been described and shown it is to be understood that if preferred but a single crank and mechanism operated thereby may be utilized.

What is claimed is:

The combination with a reciprocating element, and revoluble means for actuating the same in one direction; of cranks on opposite sides of and revoluble with said means, pivoted hangers extending downward into the paths of the respective cranks and disposed to be shifted in one direction thereby to return the reciprocating element to its initial position, said hangers having slotted portions, means extending from the reciprocating element and into the slotted portions, and means for automatically assisting the revoluble means in returning the hangers and the JAMES WILLIAM HAMILTON- Witnesses:
